• FFmpeg file not found exception, No such file or directory

  16 avril 2020, par Sagar

  I am getting the No such file or directory exception on video trimming.

  



  video path : /storage/emulated/0/Pictures/Instagram/Fast & Furious 7 - Get Low Extended Version Video.mp4

  



  file name : Fast & Furious 7 - Get Low Extended Version Video.mp4

  



  and ffmpeg searching for only Fast in/storage/emulated/0/Pictures/Instagram/Fast: No such file or directory


  



  I have found the issue, it is causing due to the file name having spaces in between them you can check in the above mentioned path and in exception.

  



  after changing the file name its working but the changing name of every file from the device it's not the right way so how can I solve this exception

• How to increase performance of bitmap drawing on Android

  20 avril 2012, par vitakot

  I created a movie player based on FFmpeg. It works fine. The decoding is quite fast, on LG P970 (Cortex A8 with Neon) I have an average 70 fps with 640 x 424 resolution video stream including YUV2RGB conversion. However, there is one bottleneck. It is drawing on Canvas.

  I use jnigraphics native library to fill picture data into the bitmap in the native side and then I draw this bitmap on Canvas in SurfaceView. It is quite simple and common approach, but the drawing takes 44 ms for bitmap with 640 x 424 resolution which reduces fps to 23 and makes this technique unusable... It takes a lot more then the whole A/V frame decoding !

  Is there any method how to draw bitmaps significantly faster ? I would prefer to render completely in the native code using OpenGLES 2, but I have read it also could be slow. So what now ?...

  How can I render bitmaps as fast as possible ?

• ffmpeg.so in PHP exec converting and no return

  13 juin 2015, par Tom

  I have seen many threads, but none working ones, so this is my issue :

  I have server installed ffmpeg (ffmpeg-php version 0.7.0, PHP Version 5.4.41) Linux CentOS 6 64bit :

  Using PHP :

  exec('/usr/lib64/php/modules/ffmpeg.so -i test.mp4 testdone.avi',$out,$ret);

  or

  exec('/usr/lib64/php/modules/ffmpeg.so -i /var/www/html/test.mp4 /var/www/html/testdone.avi',$out,$ret);

  or

  exec('/usr/lib64/php/modules/ffmpeg.so -i /var/www/html/test.mp4 /var/www/html/testdone.avi'.' 2>&1',$out,$ret);  

  the ffmpeg is actually found, but always returns : array(0) { } int(11) and with 2>&1 returns array(0) { } int(139) and does not return anything else like testdone.avi in the directory or -version (in the directory). Directories /var/www/html/ are set to 777.

  Thank you, should I hire someone to fix this or am I missing something in PHP.
